Paramecium

Instructions: Read the paragraph and answer the questions.

Paramecia are unicellular, animal-like protists. The hairlike cilia sweep back and forth to aid in movement of the paramecium as well as guide food into its oral groove. From the oral groove, food is encapsulated in food vacuoles where it is digested as it moves through the cytoplasm. Waste is eventually released through the anal pore. Contractile vacuoles help maintain osmoregulation by expelling water and waste products from the organism. Paramecia have two types of nuclei, a macronucleus for controlling the organism and a micronucleus, which assists in reproduction. Paramecia reproduce through division, known as binary fission, and new genetic material can be introduced via conjugation.
